anyone can help me to fix some error with regards to this project... I am using Visual Basic 6 and i try to use the sample accompany to this.. which is the Visual Basic Project include in this Free FingerPrint Verification SDK.. I am using Digital Persona Finger Print Recognition System ( U are U 4000B Reader ) I already install Digital Persona and create default database Then successful enrollment and verification of finger print is done then i close the project ... but when i try to open the project again an error occurs

this is an error :

Run-time error '-91 (ffffffa5)':NffvInitializeA:Win32 error in one of Neurotec modules

can you anyone help me to fix this problem.. please.. Thanks in advance Hope you reply as soon as possible.. Thanks again

Could you provide more details on your issue? Have you modified the sample source code? You mentioned that you have created default database. How was it done?It could be a situation that database is corrupted. So could you try to delete FingerprintDB.vb6.dat and UserDB.vb6.dat files from bin folder?

but i have another problem with regards to this... when i add another form.. which is log in form.. to be specific i want to add login form.. form the beginning then when login is succesful why does the form didnt continue..

like this.. the first form will be.. ChooseScannerForm.. then LogInForm that i created... after this LogInForm.. this will be followed by MainForm.. but the MainForm doesnt appear.. what do you think is the problem with that...

and also.. i try to add animation rather i add another form just for introduction an animation thing.. and after that.. the same problem occur.. main form doent continue..

hello...I' ve try to develop application using visual basic 6 too, but i use the Hongda S680 finger print...i've install my finger scanner, but when i try to run my application it throw error : "Failed to Enroll : No Scanner ".Why it can not detect my scanner....Can You Help Me Please ??

Hello Bayu,

Is the scanner recognized by Neurotechnology samples/tutorials? Please contact support@neurotechnology.com and specify all the details on problem your are facing.

I've been having some trouble getting the free fingerprint sdk integrated with an existing application. I am able to run the samples w/out getting this error, but continue to receive this error when I utilize the code in an existing winforms app. (.NET)

I'm getting this error:Unable to load DLL 'Nffv.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

from this line of code:engine = new Neurotec.Biometrics.Nffv(FingerPrintUtilities.GetDatabase(), string.Empty, "Upek");

"FingerprintUtilities" is a class I created to handle some of the basic utilities such as returning the path to the the text file that acts as the database. So "GetDatabase()" returns a string.

"engine" is defined in the class as: "public Neurotec.Biometrics.Nffv engine;"

The "Neurotec.Biometrics.Nffv.dll" DLL is present and is referenced. For giggles, I found the "Nffv.dll" dll and referenced it, but I then received errors about the licensing service not running. I'd like to use the free version as it more than accomplishes what we're trying to do.

Any ideas off the top of your head as to why I may be receiving this error or how I can get more detailed information on why I'm receiving this error?

Hello Craig,

You should have Neurotec.Biometrics.Nffv.dll, Nffv.dll and NffvServer.exe for application your are developing, The best way is to put them to the same directory where your application's executable is. In our SDK, the required files and executable application are in "FreeFingerprintVerificationSDK\bin\Win32_x86" directory.

I am having this error on my application Load Exception: Could not load file or Assembly 'Neurotec.Biometrics.Nffv.dll', Version=1.0.0.0, Culture=neutral, PublicKey Token= ea4ecf06177ea613, or one of its dependencies.

Hello,

please check if the Nffv.dll is loaded with your application. Neurotec.Biometrics.Nffv.dll depends on the Nffv.dll. The best solution in this case is to copy all dlls from the SDK folder to your application output folder.

HelloI'm experimenting with Free FingerPrint Verification SDK and have one question.How can I remove user from database if I don't need his enrollment information more?I can't see any method to do this. Could somebody help?Thanks

Hello,each sample provided with the SDK shows how to delete the user from the database. Please check it.

Hello,

Free Fingerprint Verification SDK can use only its proprietary database. If you need to use any other database then you need to consider VeriFinger 6.2 SDK usage.

Please i am kind of new to Visual Basic .Net but i need to integrate finger print reader into a project i a developing.I have done some research and found out i need sdk to do that which i downloaded you free version .I have been able to run your sample but my problem is to be able to write same codes so that i can scan a finger but i dont really i understand your codes can you please help me do this i would be very grateful.All i need is to get the finger print from the scanner like and to compare two images .Thank you.

Hello,

Free Fingerprint Verification SDK does not allow to save the scanned image. Also it has limitations on the size of the database. You can consider usage of the VeriFinger 6.2 Standard SDK, which will allow you to save scanned images and have unlimited database. This SDK includes samples and tutorials, which allows customer to see how everything can be implemented.

Please i have this problem,I have been able to work on my fingerprint project with your free SDK but the problem i have now is.When ever i enroll users to the fingerprint database .dat file it saves up to a maximum of 10 user on the 11th users,it gives me an error message(Invalid operation executed in one of the neurotec module code-7.Please help me fix the problem i have tried to debug all day but its still not working for me.Please help me am stuck and need your help..Please i need help i want to be able to enroll as many users as i want.

Also i really want to understand what is going on within the dat file which seems to be storing the fingerprints.Thank you

FFV SDK is intended to be used only on systems where maximum 10 fingerprints will be enrolled. It is a limitation of this SDK. If you need to enroll more users then consider VeriFinger 6.3 SDK usage. Comaprison between FFV SDK and VeriFinger SDK can be found here.

Hi. First of all Thanks to that great person who create this website.I'm new to biometric, but i have a little experience in java programming. My question is it if is possible to ask. I have download FFv sdk than installed after that from all program i go to the java sample place , the two build.bat files i runed before from cmd comand,then after from java sample when I try to run NFFvSample.html I get the following error , Could you direct me please what i was doing wrong? This is error from NFFvSample.html

Hi,

which browser are you using when you experience this issue?What version of Java Runtime are you using?

FFV SDK engine saves only numeric ids. So you should save the name of users and related ids in the separate database or file. So before enrolling you can check if such name exists in the database. C# uses the xml as the database for user names keeping. So you can search it and compare names.

Thanks,Croc

You need to specify the java.library.path when executing. i.e. java -Djava.library.path=PATH_TO_NffvJavaNative.dll -jar NffvSample.jar.Also you can specify the path to NffvJavaNative.dll in the PATH environmental variable too.

Please am quite new to the SDK but have a project to deliver urgently, i am using the free fingerprint verification sdk and developing using C# but the problem is when i tried the sample application i was unable to find the the fingerprint device i am using and i had installed secugen hamster plus, i really don't know what to do.

please check if the Nffv.dll is loaded with your application. Neurotec.Biometrics.Nffv.dll depends on the Nffv.dll. The best solution in this case is to copy all dlls from the SDK folder to your application output folder.

I am having the same problem above, but if I copy the dlls from the sdk folder, the problem still continues. However, I am using VS 2008, and I only have bin folder.

Hello,

Free Fingerprint Verification SDK does not provide support of the standard templates (ISO or ANSI). If the support of standard templates is needed, then the Fingerprint BSS component is required; the component is available in VeriFinger Extended SDK or MegaMatcher SDK.

Thanks for your answer. This BSS component exists with independent componente to test in free SDK??
